BOTTLE-CLEANING MACHINE.

Specification of Letters Patent.

Patented March 24. 1908.

Application filed November 13, 1906. Serial No. 343,192.

To all whom it may concern:

Be it known that I, ANDERs ANDERSEN PINDSTOFTE, manufacturer, subject ofDenmark, residing at No. 62 Frederiksberg all, Frederiksberg, Denmark,have invented new and useful Improvements in Bottle-Cleaning Machines,of which the following is a specification.

The invention relates to bottle cleaning machines for simultaneouslycleaning the interiorv and exterior of the bottles. The bottles areplaced on conveyer trucks or in carriages which carry them to and fromthe quickly rotating brush s indles intended for internal cleaning, andit as for its object to provide means by which the bottles are caused torotate during the cleaning.

A constructional form of the invention is illustrated by way of examplein the accompanying drawings in which,

Figure 1 shows a side elevation of a bottle cleaning machine providedwith the improved means, Fig. 2 is an end view of the machine, someparts being omitted, and Fig. 3 is a detail view of one of the conveyertrucks or carriages and the device for rotatingJthe bottles duringcleaning.

ike reference numerals refer to like parts throughout the specification.

a is the frame of the bottle cleaning machine having rails 79 for therollers or wheels of the conveyer trucks or carriages 0 each of whichcarries one or more bottles d to and from the swiftly rotating brushspindles e intended for the internal cleaning of the bottles.

In the front of each carriage c is arranged a guide carriage f, whichalso runs upon the rails b and which serves to maintain the bottles inproper alinement with the brush spindles e. A drawbarlq is fixed to eachcarriage c and a drawbar h to each guide carriage The lower forked endsof these bars engage with a bar j which is inserted in a chain *5.Adjustable stops upon the bar 7' cause the drawbar and thereby thecarriage to move with the chain to and from the rotary brush spindles.The chain 1', is passed around two chain wheels is and Zmounted in theframe a. The chain is fixed to the wheel Z.

A pin Z upon the chain wheel Z is connected by a rod m with a pin a upona disk n, which latter is mounted upon a vertical shaft 0. The shaft 0is intermittently rotated by means of a constantly rotated shaft 10,

which by means of a pinion gear and a roller friction coupling of anywell known construction rotates vertical shaft 0. The shaft 1) is drivenby belt connection with the main driving shaft g, which is mounted inthe to of the frame a and. which is provided with loose and fixedpulleys r. The disk n is rovided with two projections s, which aternately engage a hook s at the end of an arm if provided with acounterweight t. arm t is fixed to a shaft or provided with a handle uby means of which the hook of the arm can be thrown out of engagementwith the projections s.

The conveyer carriages c are provided with bottom brushes y which duringthe cleaning bear against the bottoms of the bottles, and also withrotatable rollers or the A like 1), which support the underside of thebottles, the sides of which are supported by rotatable rollers w alsomounted upon shafts fixed to the rear-frame of the carriage. The necksof the bottles are supported by supports n adjustably fixed to the.front of the carriage.

The frame a carries four uprights 2, which support three plates 2, 3,and 4. The plate 2 carries the hollow shafts, in which the brushspindles e are fixed, said shafts being rotated from the main drivingshaft 9, the bearings of which are carried by the plate 4. The plate 3is adj ustably fixed to the uprights 2 by means of nuts and carries twoshafts 5 which are rotated from the main driving shaft g,

and which shafts carry one or more rollers or I disks 6 of elasticmaterial such as india rubber, bristles, leather or the like. Therollers or disks 6 are so formed that they will come into contact withthe outer surface of the bottles when the conveyer carriages havecompleted their forward movement, but not before, and that they willrelease the bottles as soon as the backward movement of the conveyercarriages commences. The rollers or disks 6 may be adjusted to the sizeof the bottles by raising or lowering the plate 3.

The two sets of carriages, each consisting of a conveyer carriage and aguide carriage, are inserted in the chain "L in such a manner, that theone set is moved forward when the other is moving backward and viceversa.

The operation of the device is as follows: The bottles are placed in therear conveyer carriage c (Fig. 1), which supports the bottles in aninclined position, so that when the bottles are inserted upon the brushspindles their The axis lie above the axis of said spindles and form anangle therewith. The handle '11, is then turned so that the projection sof the disk n and consequently said disk is released and rotated untilthe second projection 8 comes in contact with the hook of the arm 25,which again is brought in normal position by its counterweight. Therotation of the disk n is transmitted to the chain-wheel Z which movesthe chain 4 thereby causing the rear set of carriages to move forwardand the forward set to move back. When the conveyer carriage movesforward with the bottles its guide carriage will guide the mouth of thebottles in alinemen-t with the brush-spindles e, and as soon as theconveyer carriage has completed the forward movement the disksor rollers6 come into contact with the outer surface of the bottles, which latterthereby are rotated-in the opposite direction of the disks or rollers 6,the result being that the bottles which are supported by the rotatablerollers 12 will be cleaned in every part of their interior. As soon asthe backward movement of the conveyer carriages commences the disks orrollers 6 release the bottles, so that the bottles are only rotatedduring the cleaning but not during their movement to and from the brushspindles. This is of very great importance as thereby the risk ofbottle-breakage during cleaning is reduced to a minimum.

I claim:

In a' bottle cleaning machine having a frame provided with horizontallyarranged quickly rotating brush-spindles for, the internal cleaning ofthe bottles, the combination with conveyer carriages carrying thebottles to and from said brush spindles and having rotatable rollers forsupporting the bottles in such inclined position that their axis liesabove and forms an angle with the axis 'of the brush spindles, of one ormore rotating cylinders of an elastic material adjustably'mounted in theframe of the machine above said brush spindles and being of such a sizethat they come into contact with and rotate the bottles, but only at themoments where the bottles are fully inserted upon the brush spindles.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
